Temperature Converter

The temperature converter allows you to quickly and accurately convert between Celsius, Fahrenheit, and Kelvin. Whether you're checking weather forecasts, cooking, or working in science, this tool handles the math instantly.

Temperature conversion is one of the most common daily calculations. With Celsius used in most of the world and Fahrenheit in the United States, knowing how to convert between them is essential for travel, cooking, and international communication.

How it works

Temperature conversions use specific formulas rather than simple multiplication factors. To convert Celsius to Fahrenheit: °F = °C × 9/5 + 32. To convert Celsius to Kelvin: K = °C + 273.15. To convert Fahrenheit to Celsius: °C = (°F − 32) × 5/9. All conversions go through Celsius as an intermediate step.

Use cases

  • Converting weather forecasts between Celsius and Fahrenheit
  • Adjusting cooking and baking temperatures for international recipes
  • Scientific calculations requiring Kelvin or Celsius
  • Understanding body temperature readings in different scales
